C64-DTV & SID
I'm really interested how close is C64-DTV SID-emulation in comparison with the real chip...
Which chip works in it: 6581, 8580, both?
Ok, since there are a lot old games in it, it's possible that emulation is more like a 6581; but what's about the filters?
Btw. The idea behind the c64-dtv seems to quite nice, but I would prefer a kind of portable SID-player.

Eh. Even the newer SID has filters!!!
And I have many C64Cs! |

The C64C does have filters, but they aren't as, uh, prominent as the older C64s (prior to June 1987 - it seems to me that was when the new 8580 based C64Cs reached Australian stores).
Martin Galway complained that the new filters were "way too open" so you could be forgiven for thinking they weren't there at all.

The DTV doesn't have filters because the poor ASIC that's being hammered as it's "heart" hasn't enough push to do cycle accurate VIC-II, full I/O, SID sounds *and* the filters. The SID that the core is modelled on is a 6581 and, barring that and the ring modulation dropping sounds from Cybernoid 2, it does an admirable job in the circumstances. |

Yes, from what I know, 1987 is correct. :) |

Looking at the SwinSID page, your wish might be in development:

Interesting concept. |

It reminds me of PC64 that emulated the SID with the Adlib FM synth. It'd probably sound better if tunes were composed directly for it.

The samples there are for the SwinSID, not for the portable SID player prototype. |

For the SwinSID itself, it might be better to think of it as a SID alternative rather than a replacement.
I've come across a few SID players for PC that used the Adlib - the emulation is far from ideal, but sometimes works well. I've found several tunes that sound different, but in a good way - rather like hearing a familiar melody played on a new instrument.
I'd also like to hear what the SwinSID would sound like with tunes arranged specifically for it. |

I've updated my SwinSID module to support pulse width efect. Now it sounds close to real SID. There are new sample music on my site.
I'am working on enhanced version of this card with more channels and effects. I will post more info here soon. |
